A calendar feed is a standing credential whose contents end up in a
third party's calendar cloud. Putting a record's cycle dates there is
the decision of the person they are about, or of the guardian of
somebody who cannot make it, and no delegate of an adult's record,
MANAGE included.
The subscription routes resolve through requireGuardianAuth instead of
requireRecordAuth("manage", "cycle"): the owner on their own record, or
a MANAGE grant on a record carrying the managed-profile marker. Every
verb follows, the revoke too. The feed re-reads the marker on each fetch
as well as the guardian's grant, so a row minted for somebody else on an
adult's record is a 404 whatever grant stands behind it. The settings
card is offered only where the routes answer.
The routes move from the delegable and MANAGE literals to the guardian
list, and the MANAGE handler inventory is back to 93.
A how-to for subscribing from Google, Apple and Outlook and what the
feed shows; a section on the reproductive-health page saying that once
it is on, the dates also sit with the calendar provider and turning it
off does not reach those copies; a reverse-proxy note with Caddy and
Nginx examples for keeping path credentials out of access logs; and
API_TOKEN_HMAC_KEY rotation named as ending every feed link.
